Dual action truck bed cover

ABSTRACT

A dual action truck cover provides two modes, actions or ways to access contents in a truck bed. Side rails can be mountable to a cargo box so as to be pivotable between a raised position to provide a rear opening in an open pivot arrangement, and a lowered or closed pivot arrangement. The side rails can be spaced apart to define an inter-rail area therebetween. A door can include a plurality of elements hingedly coupled together and extending between the side rails and movable between a closed door arrangement wherein the elements cover the inter-rail area, and an open door arrangement in which the elements are positioned to permit access through the inter-rail area. The door can move between the open and closed arrangements by rolling up the hingedly coupled elements together or folding the elements together.

CROSS-REFERENCE TO RELATED APPLICATIONS

This application is a continuation of U.S. application Ser. No.15/048,028, filed on Feb. 19, 2016 (now U.S. Pat. No. ______, issued______), which claims the benefit of U.S. Provisional Application No.62/137,907, filed on Mar. 25, 2015. The entire disclosures of the aboveapplications are incorporated herein by reference.

FIELD

The present disclosure relates generally to the field of pickup truckaccessories. More particularly, the present disclosure relates to acover for a truck bed on a pickup truck. Specifically, the presentdisclosure relates to a dual action cover mountable to a pickup truck.

BACKGROUND

Pickup trucks include an open truck bed mounted on a frame behind apassenger cabin. These types of trucks are known for their versatilityand ability to haul items in the truck bed or tow implements from ahitch coupled to the frame. Furthermore, these pickup trucks are oftenuseful to a wide range of operators, from commercial contractors haulingheavy equipment, to weekend users hauling grass clippings and mulch.

In some environments, it is beneficial to close the truck bed in orderto protect contents stored therein. There are two main accessoriessomeone can attach to their truck to protect the contents within thetruck bed. The first way of protecting contents inside a truck bed isthrough the use of a camper shell (also known as a canopy, and sometimestopper, cap, bed cap, box cap, or simply shell) which is a small housingor rigid canopy. The camper shell housing is usually made of fiberglassor aluminum and is mounted atop the pickup truck bed. It usually coversthe entire bed of the pickup truck, and is large enough to be used forcamping purposes. Even though use for camping may have been its initialpurpose, it now seems most often to be used for utility and storagepurposes—particularly the protection of cargo from the elements andtheft.

Another way of protecting contents inside a truck bed is through the useof a truck bed cover (also known as a tonneau cover), which is alow-profile truck accessory that mounts atop the truck bed andsubstantially covers the same. A truck bed cover does not rise up withthe substantiality of a truck cap; rather, it is designed to nest atopthe truck bed at a height similar to the top of the truck bed sidewalls.These truck bed covers are ordinarily constructed with aluminum framesand a fiberglass or plastic shell. Then, when the user desires to accessthe truck bed, the cover provides an access opening to the truck bed.One form of access opening associated with truck bed covers is throughthe use of hydraulic piston-cylinder actuators pivoting the truck coverbetween an open and closed position, wherein the user has access to thetruck bed when the cover is in the open position. Another form of accessopening associated with truck bed covers is through the use of ahorizontally mounted retractable door moveable in a manner similar tothe action of a roll-up door between an advanced position and aretracted position, wherein the user has access to the truck bed whenthe door is in the retracted position.

Issues continue to exist with truck covers as they are currently knownin the art. Namely, truck covers only provide a single way of accessingthe truck bed; either with the open/closed piston-cylinder actuatedconfiguration or the advanced/retracted roll-up door configuration.Thus, a need exists for a truck cover that can provide a plurality ofways in which a user can access the truck bed. The present disclosureaddresses these and other issues.

SUMMARY

This section provides a general summary of the disclosure, and is not acomprehensive disclosure of its full scope or all of its features.

DETAILED DESCRIPTION

As depicted throughout the figures, an example of a dual action truckbed cover of the present disclosure is generally indicated at 10. Truckbed cover 10, also referred to generally as cover 10 or truck cover 10includes a frame 12, a door 14, a base 16, a hinge assembly 18, and adual action latch assembly 20. Frame 12 is moveable between open andclosed pivot positions and, furthermore, door 14 is moveable betweenadvanced or closed door and retracted or open door positions.

As depicted in FIG. 1, cover 10 is shown in a closed position carried bya truck 100 and a portion of cover 10 extending over the truck bed 102.Base 16 of cover 10 is mounted adjacent the top bed walls of the truckbelow the frame 12, with frame 12 carried above base 16.

As depicted in FIG. 2 and FIG. 3, in some embodiments the truck cover 10includes a forward end 22 spaced opposite a rear end 24 defining alongitudinal direction therebetween. A left side 26 is spaced apart andopposite a right side 28 defining a lateral direction therebetween. Atop 30 is spaced apart and opposite a bottom 32 defining a verticaldirection therebetween.

In some embodiments, frame 12 includes a first longitudinally extendingmember 34 spaced apart and generally parallel to a second longitudinallyextending member 36. Longitudinal members 34, 36 define a portion of afirst or upper inter-rail area or opening 38 therebetween. First andsecond longitudinal members 34, 36 are parallel and extend substantiallyfrom front end 22 to rear end 24. Each of the first and secondlongitudinal members 34, 36 is entirely above base 16 and thereforeconstitutes upper side rails 34, 36. A first lateral member 40 extendslaterally between forward ends of the first and second longitudinalmembers 34, 36. A first or upper laterally extending or lateral member40 bounds a forward end of opening 38. In one particular embodiment,lateral member 40 is fixedly secured to each of the first and secondlongitudinal members or upper side rails 34, 36. First and secondlongitudinal members 34, 36 and lateral member 40 are preferablyconstructed from aluminum yielding strength to truck cover 10 whilesimultaneously being lightweight in construction.

In some embodiments, each longitudinal member 34, 36 defines alongitudinally extending C-shaped channel therein. A first C-shapedchannel 42 (See also FIG. 7) extends longitudinally from forward end 22to rear end 24 in first longitudinal member 34. A second C-shapedchannel 44 extends from forward end 22 to rear end 24 in secondlongitudinal member 36. Each channel 42, 44 face first opening 38 andbounds the respective left and right sides of the opening. As will bedescribed in greater detail below, first channel 42 and second channel44 receive respective left and right edges of door 14 permitting door 14to slide along the aligned channels 42, 44. While reference is made tocertain elements along one side of truck cover 10, it is to be clearlyunderstood that duplicated elements thereof may exist and are similarlysituated and connected along the other side of truck cover 10.

As depicted in FIG. 4 through FIG. 8, in some embodiments, base 16includes a first or left longitudinal member or side rail 54 and asecond or right longitudinal member or side rail 56 defining a second orlower inter-rail area or opening 58 therebetween. Each of the first andsecond longitudinal members 54, 56 is entirely below the frame 12 andtherefore constitutes lower side rails 54, 56. Second opening 58 ispositioned below frame 12 and is aligned with opening 38 defined byframe 12, each opening 38, 58 is configured to provide access to apickup truck bed 102 when either frame 12 is in the open position ordoor 14 is in the retracted position. Longitudinal members 54, 56 ofbase 16 extend longitudinally spaced apart and generally parallel fromfront end 22 to rear end 24. Longitudinal members 54, 56 are preferablyconstructed from a lightweight aluminum material similar to that of base12 and hinge assembly 18.

A second or lower lateral member 60 may extend between longitudinalmember 54 and longitudinal member 56 adjacent each forward end. Whencover 10 is in the closed position, lateral member 40 is disposed abovelateral member 60. Base 16 may further include a coupler 62 for couplingeach longitudinal member 54, 56 to the pickup truck. Downwardlyextending housing 66 includes a laterally extending forward wall 68positioned forwardly from a laterally extending rear 70 defining aportion of a chamber 72 therebetween. Housing 66 further includes abottom wall 69 and sidewalls 71. A spindle 74 extends laterally throughchamber 72 adjacent the middle of the chamber such that when frame 12 isin the closed position but door 14 is in the retracted position,portions of door 14 are wound about spindle 74 as will be described ingreater detail below.

In some embodiments, hinge assembly 18 couples frame 12 to base 16adjacent the forward end of frame 12. A flange 46 extends downwardlyfrom a rigid connection with longitudinal member 34. A first leg 48 ispivotably connected to flange 46 and extends from flange 46 towards base16. A second leg 50 is pivotably connected to flange 46 and extendstowards base 16. When viewed from the side, a portion of second leg 50is positioned forwardly from first leg 48 when frame 12 is in the openposition. Each first and second leg 48, 50 is a J-shaped configurationpositioned in a mirrored configuration for receiving a portion of theother leg nestingly therein when frame 12 is in the closed position. Aflange 64 extends from first a longitudinal member 56 on base 16pivotably coupling the bottom ends of first leg 48 and second leg 50 tobase 16. A downwardly extending housing 66 is positioned forwardly offlange 64.

As depicted in FIG. 6 through FIG. 8, in some embodiments, coupler 62includes a clamp plate 130, an elevator carriage bolt 132, a verticalfirst slot 134, a longitudinal second slot 136, a securing bolt 138, andan insert 140. Clamp plate 130 is secured via bolt 138 to hook member142 of pinch lip 144 of truck bed. An upper lip 144 of truck bed issandwiched between hook member 142 and clamp plate 130. Bolt 138 extendsthrough vertical slot 134 at a vertical height lower than longitudinallyextending second slot 136. A head 145 on carriage bolt 132 is disposedwithin a recess as bolt 132 extends through second slot 136, wherein thesquare neck portion of bolt 132 rests squarely in the slot. Insert 140is held in channel 92 and threadably receives the threaded portion ofbolt 132. Insert may be held in channel 92 by set screw 146.

In some embodiments, a hydraulic actuator 52 is connected to frame 12 ata rear end and connected to base 16 at a forward end, wherein theforward end of actuator 52 is positioned rearwardly from first leg 48.Actuator 52 is a hydraulic piston and cylinder actuator configured toassist in the lifting of frame 12 from the closed position to an openposition.

As depicted in FIG. 20 and FIG. 21, in some embodiments, frame 12 can bepivotable via rotation about a stationary pivot axis A. In addition, theframe 12 can be pivotable about a non-stationary or movable axis, suchas where both the forward and rear ends of the frame 12 translate androtate with the rear end being raised a greater distance than theforward end as they rotate as depicted in FIG. 1 and FIG. 14. Asillustrated in FIG. 20 and FIG. 21 the stationary pivot axis A, extendslaterally, and substantially perpendicular to the longitudinal first andsecond side rails 34, 36 and to the longitudinal axis of the truck L. Aforward end of the frame 12 can be pivotably coupled to the forward endof the truck box 102. For example, a laterally extending piano hinge 172can couple the lateral member 40 of frame 12 to the forward wall 68 ofthe housing 66. As also depicted, in some embodiments, the gas actuator52 can be coupled between the frame 12 and base 16 via a plurality ofpivotably coupled link arms 52, 53.

As depicted in FIG. 2 through FIG. 8, in some embodiments, door 14includes a plurality of tandemly aligned panels 76 extending fromforward end 22 to rear end 24 and extending from left side 26 to rightside 28. Panels 76 include a lateral width that is greater than alongitudinal width. This configuration causes door 14 to be shapedsimilar to a plurality of slats hingedly connected 65 to each other attheir respective forward and rear ends. The hinge configuration 65 isaccomplished by a laterally extending channel in each panel filled withseal 89 to receive a complementary channel on the adjacent panel. Endcaps 99 connect to the lateral ends or longitudinal sides of each panel76 and held in channel 44 by downwardly extending stop 97. End caps 99are constructed from a polymer material that slides along metal in asmooth manner. Each panel 76 includes a left end and a right end whereintheir respective left and right ends slide along first and secondchannels 42, 44 respectively.

As depicted in FIG. 22 and FIG. 23, in some embodiments wheels 150, 152can be coupled to lateral ends or along opposing longitudinal sides ofthe door 14 or door panels, slats, or rectangular elements 76. Thewheels 150, 152 can facilitate movement of the door 14 between the openand closed door positions or arrangements. In some cases, the wheels150, 152 or the end caps 99 can cooperate with the side rails 34, 36 ofthe frame 12 to help maintain the desired lateral distance and parallelorientation between the side rails 34, and 36. For example, as shown inFIG. 22, wheels 150 coupled to opposite longitudinal sides of the doorslats, or rectangular elements 76 can have a circumferential groove 154.One or more protrusions 156,158 of the upper side rails 34, 36 canextend into the circumferential groove 154 of wheels 150 coupled to afirst longitudinal side of the door slats, or rectangular elements 76and received within the first longitudinal side rail 34. Similarprotrusions 156, 158 of the second longitudinal side rail 36 of theframe 12 can extend into the circumferential groove 154 of wheels 150coupled to a second, opposite longitudinal side of the door 14. Thus,engagement of the protrusions 156, 158 within the groove 154 of thewheels 150 helps maintain the desired lateral distance and parallelorientation between the upper side rails 34, 36.

As another example depicted in FIG. 23, wheels 152 coupled to oppositelongitudinal sides of the door slats, or rectangular elements 76 can becaptured between a plurality of protrusions 160, 162 of the respectiveupper side rails 34, 36. In the depicted example, the protrusions 162,164 of the upper side rails 34, 36 define a channel 166 that retains thewheels 152. Respective engagement between opposing protrusions 160, 162and the opposite sides 168, 170 of the wheels 152 help maintain thedesired lateral distance and parallel orientation between the upper siderails 34, and 36.

In some embodiments, both wheels 150 having a circumferential groove 154receiving groove protrusions 156, 158 of the upper side rails 34, 36 andwheels 152 with opposite sides 168, 170 captured between opposingprotrusions 160, 162 of the upper side rails 34, 36 can be usedtogether. For example, one or more of the door slats or rectangularelements 76 can have both types of wheel/protrusion arrangements on eachof the longitudinal sides of the slat 76. As seen in FIG. 22, the upperside rails 34, 36 can include both the opposing protrusions 160, 162 forcapturing the wheel 152 therebetween and protrusions 156, 158 extendinginto the circumferential groove 154 of the wheels 150. As anotherexample, alternating door slats or rectangular elements 76 canalternatingly have the grooved wheel and protrusion arrangement or theside-captured wheel between opposing longitudinally extendingprotrusions. In some cases, selected slats or rectangular elements 76adjacent the rear of the door 14 will include at least one type ofarrangement to help maintain the desired lateral distance and parallelorientation between the upper side rails 34, 36, while selected slats orrectangular elements 76 adjacent a forward end of the door 14 may notinclude any type of such arrangements.

As depicted in FIG. 9, in some embodiments, a rearmost panel 85 of thedoor can include a downwardly extending flange 83 that defines the rearend of door 14. Flange 83 contacts the tailgate 117 when door 14 is inthe advanced position and the tailgate 117 is closed. Door 14 ismoveable between an advanced position (FIG. 1) and a retracted position(FIG. 16). As depicted in FIG. 4, in some embodiments, the plurality oftandemly connected panels 76 are adapted to wind about spindle 74 in theretracted position. A pair of wheels 94 may be disposed adjacent the topof housing 66 between walls 68 and 70. Wheels 94 may be rotatablymounted on each respective left and right side of truck cover 10. Wheels94 assist in the movement of door 14 partially therearound as door 14winds about spindle 74. A door stop 93 may be positioned to stop secondlatch 88 and hold door against the winding force of a torsion spring 75.

As depicted in FIG. 9 through FIG. 13, latch assembly 20 includes amounting bracket 80, a laterally extending rod 82, a latch 84, a lever86, and a second latch 88. Mounting bracket 80 is coupled near the rearend of longitudinal member 56 of base 16. In one particular example,bracket 80 is coupled to an insert 90 disposed within a channel 92defined by longitudinal member 56 of base 16. Channel 92 is a C-shapedchannel configured to receive insert 90 therein and channel 92 is belowchannel 42 on longitudinal member 34 of frame 12. The lateral rod 82extends inwardly towards the center of the truck from bracket 80terminating at an end and having a generally circular cross-section.

Latch 84 is spring-loaded and able to releasably secure rod 82 byselective movement of operatively coupled lever 86. The movement oflatch 84 is associated with a first action operatively coupled to theopened and closed position of frame 12. The actuation of lever 86 in afirst direction may release latch 84 to a neutral position allowingframe 12 to lift up, causing latch 84 to pivot vertically downwards asframe 12 moves from the closed position to the open position. In areverse manner, as frame 12 is moved from an open position towards aclosed position, latch 84 contactingly engages lateral rod 82 topivoting upwards as frame 12 moves downward and the neutral engagementof lever 84 allows rod 82 to pass thereby. Then the spring engagementlocks lever 84 in place securing frame 12 in the closed position.

As depicted in FIG. 11, movement of second latch 88 in the seconddirection is associated with a second action and is operativelyconnected to the movement of door 14 between an advanced position and aretracted position. As second latch 88 is moved in a second directionagainst a spring force 95, an engagement with a catch plate 87 isreleased, ordinarily securing door 14 in the advanced position, allowinga user to push door 14 towards the forward or front end 22, sliding saiddoor 14 along first and second channels 42, 44, wherein the plurality ofpanels 76 are wound about spindle 74 inside chamber 72. Catch plate 87tapers or is sloped when viewed from below. The sloped angle of catchplate 87 pushes a distal end of latch 88 inwardly against spring 95 asdoor 14 moves toward the advanced position.

In one particular embodiment, a rotatable handle 110 operatively coupledwith pushrod 112 may be a part of latch assembly 20. The operativecoupling of handle 110 to pushrod 112 is a rotation-to-translationmanner as one having ordinarily skill in the art would understand. Ashandle 110 rotates, it imparts a linear translation of pushrod 112. Aspushrod 112 linearly translates, the end of pushrod 112 may contactlever 86 to release latch 84 allowing frame 12 to move from the closedposition to the open position.

As depicted in FIG. 24, some embodiments can include an exterior orfirst latch handle 110 on an exterior side 178 of the cover 10 orotherwise positioned to be accessible from the exterior of the cover 10when the frame 12 is in the closed pivot arrangement or position and thedoor 14 is in the advanced or closed door position or arrangement. Asecond latch handle 182 can be provided on an interior side 180 of thecover 10, or otherwise positioned to be inaccessible from the exteriorof the cover 10 when the frame 12 is in the closed pivot position orarrangement and the door 14 is in the advanced or closed door positionunless the tailgate 117 is in an open position.

In some embodiments, the exterior latch handle 110 can operate to latchthe frame 12 in the closed pivot position or arrangement and interiorlatch handle 182 can operate to latch the door 14 in the closed doorposition or arrangement. For example, ends of pushrods or linkages 184operably coupled to the exterior latch handle 110 can operably engagethe lower side rails 54, 56 of the base 16, directly or via a latchmechanism or bracket 188, when in a latched position or arrangement toprevent pivoting of the upper frame 12 relative to the lower base 16.When the exterior latch handle 110 is rotated or otherwise moved to anunlatched position, the ends of pushrods 184 can operably disengagelower side rails 54, 56, allowing the frame 12 to be pivoted to the openpivot position or arrangement.

Similarly, ends of pushrods or linkages 186 operably coupled to theinterior latch handle 182 can operably engage upper side rails 34, 36 ofthe upper frame 16, directly or via a latch mechanism or bracket 190,when in a latched position or arrangement to prevent movement of thedoor 14 relative to the frame 16 toward the open door position orarrangement. When the interior latch handle 182 is rotated or otherwisemoved to an unlatched position or arrangement, the ends of pushrods 186can disengage upper side rails 34, 36, allowing the door 14 to be movedtoward the retracted or open door position or arrangement. In somecases, the exterior latch handle 180 can be a keyed or lockable latchhandle and the interior latch handle 182 can be a non-keyed ornon-lockable latch handle interiorly adjacent the keyed tailgate 117.

Truck cover 10 can selectively permit access to the truck bed or box 102in two different manners. Access to the truck bed or box may first beaccomplished by raising frame 12 from the closed position, in which theside rails of the frame 12 can be substantially horizontal to the toprail of the truck bed 102, to a raised position, in which the side railsof the frame 12 are angled relative to the top rail of the truck bed.When frame 12 is raised in the open position, a user may then reach intothe truck bed through second opening 58 to access items stored therein.The other manner in which a user can access the truck bed 102 via thecover 10 is by closing frame 12 such that it is substantially parallelto the top rail of the truck bed, then moving door 14 from the advancedposition to the retracted position. The movement towards the retractedposition reveals opening 38, allowing a user to access the contentsstored in the truck bed 102 through the revealed opening 38 incommunication with inter-rail opening 58.

In some embodiments, the dual action, or dual movements, of truck cover10 are operatively controlled by latch assembly 20. In one particularembodiment, the lever 86 on latch assembly 20 may be actuated indifferent directions wherein each directional movement of lever 86 onlatch assembly 20 is associated with one of the two movements mentionedabove. So, for example, actuation of lever 86 in a first direction mayrelease frame 12 from its locking engagement with base 16 allowing frame12 to move from the closed position to the open position (e.g., a firstaction). An actuation of lever 86 in a second direction opposite that ofthe first direction may be associated with releasing door 14 from itslocking engagement so that it may be retracted from the advancedposition to the retracted position (e.g., a second action). Statedotherwise, a first action of the latch assembly 20 is associated withmovement of the frame relative to truck bed, and a second action of thelatch assembly 20 is associated movement of the door relative to theframe.

In another embodiment, the first and second latches 84, 88 may becontrolled by separate movements. As provided in FIG. 10, pushrod 112actuates lever 86 to release 84, while a second action not performed bypushrod 112 moves latch 88. In this embodiment, the release of firstlatch 84 is associated with moving frame 12 from the closed to theopened position. The release of second latch 88 from its engagement withcatch plate 87 is associated with the moving the door from the advancedto the retracted position (See FIG. 11).

Additionally, a lock on the latch assembly 20 may secure the door 14 inthe advanced position when the frame 12 is in the open position, and thelock may secure the frame 12 in the closed position when the door 14 isin the retracted position.

In operation and with reference to installation of truck cover 10 ontothe truck, and more particularly the truck bed, in some embodiments,longitudinal members 54 and 56 are mounted adjacent the top rails of thetruck bed in a fixed manner. In one particular embodiment, coupler 62couples longitudinal member 54 to the left side of the truck bed and acoupler 62 couples longitudinal member 56 to the right side of the truckbed. Second lateral member 60 may be connected to a front lateral wallof the truck bed 102. During installation, housing 66 can be positionedwithin the truck bed 102 adjacent the front end of the truck bed 102extending downwardly from forward end of the cover 10. In someembodiments, the housing 66 can be coupled to and extend downwardly fromthe front ends of the longitudinal members 54, 56 of the base 16 orotherwise fixed to the truck box 102, so that the housing 66 remainsfixedly positioned within the truck box 102 when the frame 12 ispivoted, as seen in FIG. 14, FIG. 20 and FIG. 21.

In operation and with reference to general performance of truck cover10, in some embodiments, a method for accessing a truck bed can comprisethe steps of: actuating a latch assembly 20 on a truck bed cover 10including a moveable frame 12 carrying a retractable door 14, the frame12 coupled via a hinge 18 to a base 16 mounted on a truck, a portion ofthe truck bed cover 10 extending over the truck bed. A first actuatingaction of the latch assembly 20 is associated with the movement of theframe 12 from a closed position to an opened position. A secondactuating action of the latch assembly 20 is associated with moving thedoor 14 from an advanced position to a retracted position. In this shownembodiment, first latch 84 is released by pushing lever 86 with pushrod122 and the second latch 88 is release by pulling it away from itsengagement with catch plate 87. The user may need to lower tailgate 117to perform some of the actions described, but there may be someembodiments where these actions can be performed with the tailgate up.

In operation and with reference to FIG. 14 through FIG. 16, hingeassembly 18 may move between a first position (the position shown inFIG. 1) and a second position (the position shown in FIG. 14). The pivotconnections of first leg 48 and second leg 50 with flange 46 and flange64 are laterally extending, allowing portions of frame 12 to rotatethereabout about one or more lateral axes. The first position of hingeassembly 18 is associated with the closed position of frame 12 and thesecond position of hinge assembly 18 is associated with the openposition of frame 12. The J-shaped second leg 50 pivotably couples frame12 to base 16 permitting entire frame 12 to be vertically above base 16when frame 12 is in the open position and hinge assembly 18 is in thesecond position. With entire frame 12 positioned above base 16, thereexists a gap between first lateral member 40 and second lateral member60. It is contemplated that while frame 12 is raised in the openposition at a vertical height greater than base 16, the door 14 is inthe advanced position preventing anything from moving through aperture38. Thus, while frame 12 is in the raised position access to the truckbed is accomplished through second opening 58 defined between the railson the base 16.

With continued reference to FIG. 14 through FIG. 16, during the movementof door 14 between the advanced position and the retracted position, aplurality of laterally extending hinges connecting panels 76 together ina tandem manner allow for the narrow panels to collapse about each othersuch that they may be wound about spindle 74 having an outer roll 73. Atorsion spring 75 may provide the urging force to wind spindle 74. Astrap 77 operatively couples roll 73 to forward end of door 14. Spindle74 may be powered by a motor or can be an idle spindle, as one havingordinary skill in the art would understand. The movement of door 14between the collapsed position and the advanced position is similar tothat of a roll-up door or curtain, selectively permitting access toopening 38 between first member 34 and second member 36. When door 14 isin the contracted position, a substantial portion of door 14 is storedwithin chamber 72 of housing 66. A control strap 115 may be attached tothe rear end of door 14 to allow a user to control the retraction ofdoor 14 about spindle 74.

As depicted in FIG. 17, FIG. 17A, and FIG. 18, in alternativeembodiments of the truck cover of the present disclosure generallyindicated at 210, a frame 212 includes longitudinally extending rails oneach side that are primarily formed from fiberglass, however aluminummay be used as well. A base 216 is mounted to the truck bed and ispreferably constructed from aluminum. A laterally extending hinge 218couples frame 212 to base 216 allowing frame 212 to pivot therearound.Each longitudinally extending member includes an upwardly facing surface250 composed of portions having different configurations.

As depicted in the cross-section view of FIG. 17A, a first portion 252of upwardly facing surface 250 is generally planar and connects to anupwardly extending second portion 254 to a slightly plateaued apexportion 256. From the apex portion 256, a third portion 258 extendsdownwardly, connected to a valley portion 260 defining a runoff channel262. A fourth portion 264 extends upward from valley portion 260. Aledge 213 rigidly connects to fourth portion 264 and extends inwardlytowards the center of the truck bed for a distance of about one, two, orthree inches terminating at an inner edge 266. Ledge 213 includes anupwardly facing top surface and a downwardly facing bottom surface andis planarly horizontal in cross-section.

A plurality of panels 215 define door 214. Each panel 215 is a generallyplanar member formed of fiberglass or other suitably understood polymeror man-made material. Panels may include a raised structural support orrib 270 extending from a front-to-back providing strength to each panel.Structural support ribs 270 may extend side-to-side, as one havingordinary skill in the art would easily understand. Furthermore, ribs 270may have a general hourglass shape when viewed from above. In this shownembodiment, ribs 270 extend upwardly a short vertical distance toprovide structural support as well. Panels 215 are connected in tandemvia laterally extending hinges 217.

The manner in which the panels 215 of door 214 may move between theadvanced position and the retracted position is via a folding manneralong or about laterally extending hinges 217. In this regard, thelateral edges 272 of the door panels 215 are not disposed in channels;rather, the door 214 rests atop ledge 213 on frame 212 on and may bereleasably secured thereto. One possible releasable securement is viahook-and-loop securing members. Alternatively, edges 272 can rest atopledge 213 free of any securing member, and, rather be held in place viapressure fit or frictional interference fit. Further alternatively,edges 272 can rest atop ledge 213 and be forcibly held in place as alock on a latch assembly 220 is locked to secure entire cover 210 in aclosed and locked position.

In FIG. 18 the door 214 is depicted in an accordion fold configurationin the open door arrangement. In such an accordion fold configuration, afirst panel 215 is adjacent the front or forward end 22, a second panel215 is hingedly coupled via a hinge 217 to the first panel, and a thirdpanel 215 is hingedly coupled via a hinge 217 in series to the secondpanel. Thus, the first panel is the forward most panel of the door 214and the third panel 215 is the rear most panel 215 of this three panelgroup. Each panel 215 comprises an upper or top surface and a lower orbottom surface and the door 214 is foldable such that the second panelrotates about 180 degrees in a first direction relative to the firstpanel so that the upper surface of the first panel 215 is positioned tooppose or face the upper surface of the second panel 215 and the thirdpanel 215 rotates about 180 degrees in a second direction relative tothe second panel that is opposite the first direction so that the lowersurface of the third panel 215 is positioned to oppose or face the lowersurface of the second panel 215.

Alternatively, the door 214 can be folded in a spiral fold configurationin the open door arrangement. In such a spiral fold configuration, afirst panel 215 is adjacent the rear end 24, a second panel 215 ishingedly coupled via a hinge 217 to the first panel, and a third panel215 is hingedly coupled via a hinge 217 in series to the second panel.Thus, the first panel is the rear most panel of the door 214 and thethird panel 215 is the forward most panel 215 of this three panel group.Each panel 215 comprises an upper or top surface and a lower or bottomsurface and the door 214 is foldable from the rear end 24 toward theforward end 22 such that the first panel is pivoted 180 degrees in afirst direction from the rear of the first panel and folded so the topsurface of the first, rear most panel 215 is positioned to oppose orface toward the adjacent top surface of the second panel 215. The foldedfirst and second panels 215 can be pivoted together 180 degrees in thefirst direction and folded onto the third panel 215 so the bottomsurface of the rear most panel 215 is positioned to oppose or facetoward the adjacent top surface of the third, forward most panel 30 ofthe three panel group.

A handle 221 (located adjacent rear end 24) may selectively actuatelatch assembly 220 to initiate either one of a first action (openingframe 212 to a position similar to FIG. 14) or a second action allowinga user to fold the panels about each other via connecting hinges 217.This allows the folded panels to be disposed in a folded and stackedconfiguration (see FIG. 18) adjacent the front end 22 of the cover 210,and in one particular embodiment the panels are disposed above frame 212adjacent the front end 22.

As depicted in FIG. 19, an alternate embodiment truck cover of thepresent disclosure may be generally indicated as 310. Truck bed cover310 may include or comprise a base member 316 mounted on a truckadjacent an upper edge defining an access opening of a truck bed; aframe 312 coupled via a first hinge assembly (the hinge assembly 18shown in FIG. 1) to the base member 316, the frame substantiallyhorizontal in a first position; a first mode for moving the frame 312from the first position to access the truck bed; and a second mode formoving the frame 312 from the first position to access the truck bed.The first mode includes pivoting the frame 312 about a laterallyextending axis on hinge assembly 18 to raise the frame 312 to an openposition (as shown in FIG. 14) and the second mode can include pivotingthe frame 312 about a longitudinally extending axis defined by secondhinge assembly 318 to raise the frame 312 to an open position (as shownFIG. 18).
